ASTM A106 Grade C (A106 Gr.C) seamless pipes are designed for high-pressure and high-temperature applications. With a higher carbon content and tensile strength than Grade A and B, Grade C pipes offer enhanced mechanical properties, making them suitable for more demanding industrial environments such as power generation, oil & gas, and refineries.

Key Features

Higher strength than A106 Gr.A or B
Excellent for elevated temperature and pressure conditions
Seamless design offers leak-proof performance
Suitable for welding, bending, flanging, and forming
Supplied with complete mill test certification
